Cure of gastric antral vascular ectasia by liver transplantation despite persistent portal hypertension: A clue for pathogenesis
Bibliographic record
Abstract
Gastric antral vascular ectasia (GAVE) is a rare cause of chronic bleeding in cirrhotic patients. It has been suggested that these gastric lesions might be related to portal hypertension, hepatic insufficiency, or both parameters. We report two cases of cirrhotic patients in whom GAVE was the source of recurrent bleeding. These patients also had complete portal vein thrombosis. Liver transplantation was performed and an end-to-end cavoportal anastomosis was performed, leaving patients with persistent portal hypertension after surgery. We observed complete disappearance of the antral lesions several weeks after transplantation, which shows that the GAVE is not related to portal hypertension but is rather a direct consequence of liver failure. Possible pathophysiologic mechanisms are discussed.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
